T 0 a/ZZ whom, it may concern,.- l

Be it known thatI, EMMANUEL T. Cook, ai citizen of the United States,residingat Alexander, in the county of Erath and State of Texas, haveinvented certain new and useful Improvements in Band-Cutters and Feedersfor Thrashers; and I do declare the following to be a full, clear, andexact description ofthe invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to letters or iigures of referencemarked thereon, which form a part of this specification.

Figure l of the drawings is a vertical sectional view of my device. Fig.2 is a plan view of the same. Fig. 3 is a cross-sectional View, andFigs. 4 and 5 are detail views.

This invention relates to improvements in band-cutters and feeders forthrashing-machines; and it consists in the construction and novelarrangement of parts, hereinafter fully described, and pointed out inthe claims.

In the drawings accompanying and forming part of this specification, Arepresents the frame of the machine, anda c side hooks at its tail, orother proper arrangement for attaching it to the thrasher. c is avertical beam rising centrally from near the front of frame A, andserving a purpose hereinafter explained.

Bis the main or driving shaft journaled transversely in proper bearingsacross the lower part of the frame A, and b b are pulleys on the same,to one side, by the former of which and a belt the machine is run fromthe thrasher, and the latter of which, by means of a pulley, c, andbelt, runs the apron C, which runs over proper end rollers, c c',journaled in the frameA. The apron is preferably made with thetransverse wooden bars c2 formingL part thereof.

D is a central crank on the driving-shaft B, which actuates the verticalpitman d, having its upper end pivoted to the front end of the lever orarm E that carries the knives. The said lever is pivoted between thearms of the forked upper ends of the beam a', and is made vertically andlongitudinally adjustable thereon by means of the holes @and the holes ein the beam and arm respectively. el is a bar above the lever E,likewise pivoted in one of t-he holes e of the beam a and adjustablevertically thereon. Y i

F F are the similar cutter-bars, having the edges saw-shaped andarranged to reciprocate alternately side by side, and to lift by'meanshereinafter described. ff are swinging bars pivoted by their lower endsto the rear ends ofthe cutter-bars, and by their upper ends to the leverE. f is a similar bar pivoted to one cutter-bar and lever E in frontofthe bar f, and f2 a longer bar pivoted to the other cutter-bar, to thelever E and end of the bar c'l opposite to the bar f. f3 are brace-rodsissuing from the barsf andfZ and serving to hold the cutter-bars side byside. The bars f, f', and f2 are so arranged with relation to the beama', lever E, bar e?, and cutting-bars, that the latter are made toreciprocate alternately while moving up and down. The band of the bundlebeing caught between the sawteeth of the two cutter-bars, isconsequently sheared off.

G G are the similar platforms which receive the bundles and direct themto the cutter-bars.

These platforms are secured opposite each other to the frame A by thesimilar springs, g g, which connect the front corners to the beam a',the similar vibrating arms, g' y', pivoted to their front corners and tothe frame, and the slotted similar arms, g2 gwhich are pivoted by theirinner ends to the rear corners of the platforms, and are attached to theframe by their slots and set-screws passing through it. The platformsmay, by means of said slots, be placed at different distances apart toaccommodate different-sized bundles, and when they have been pushedslightly downward by the action of the bundles and mechanism and rotatedslightly on the arms g and g2 ,the springs g will return them to place.g3 are the inwardly-extendingiingers ofthe platform, which fingers catchand hold the grain and allow the cutting-bars to act between them.

H H are swinging bands or straps of leather or other suitable materialfixed one on each side and within the frame A at its tail end, and h hare parallel rollers journaled in bearings flxed to said straps. Thestraps and rollers are so arranged in relation to one another and to theapron as to keep the grain compressed as it passes out of the binder tothe thrashingmachine.

IOO

I is a crank made on the shaft B at the end opposite the pulleys b andb, and i is a horizontal connecting-rod actuated-that is,reciprocated-by said crank.

5 J is a vertical shaft oscillating in proper bearings fixed to theframe and having standi ing out from it near its foot the crank-arm j,

which connects by its outer end and is vibrated by the rod 1l. j' is asimilar crank-arm io standing in from theshaft J near itstop above itsupper bearing.

Kis a transverse reciprocating rod, one end of which pivots over the endof the crankarm j and is actuated thereby, and the other i5 end passesover and is supported by a roller, Vk, having bearings in the oppositeside of the frame. lc' is a vertical rod depending from the rod K nearthe center of the machine and serving by the transverse motion impartedto 2o it by the rod K to spread the ends of the bundles so that they canbe more readily cut.

In operating the machine after it is attached by the hooks a a to thethrashing-machine, the bundles are run uponthe platforms G and 25 falldown upon the points g3. The action of the cutter-bars nonT comes intoplay, severing the bands and allowing the loosened grain to fall upontheapron, which carries and delivers it to the thrashing-machine. Therollers 71, lz

3o press down on thegrain as it passes outI of the band-cutter and makeit deliver more com pactly to the cylinder of the thrasher. The

cutter-bars are made long enough to engage andY cut the band Whereverthey may fall upon 3 5 the platform.

Having thus described my invention, what I desire to secure by LettersPatent isl. In a band-cutter for a thrasher, the combination, With themain frame A, main shaft B, platformsG G, and mechanism adapted andarranged to cut the bauds, of the crank I, rod i', oscillating shaft J,provided with the crankarmsjandj, reciprocating rod K, and depending rodk', substantially as specified.

2. In a band-cutter fora thrashing-machine, the combination, with themain frame A, platforms 'G G, and reciprocating cutter-bars F F, of themain shaft B, crank D, pitman d, bars E e2, and swinging straps or barsf, f', and f2, substantially as specied.

3. The combination, in a band-cutter, with the main frame and theplatforms G G, of the spring g, vibrating arms g, and slotted arms g2,adjustable ou the main frame, substantially as specified.

4C. The combination, with the main frame, of the crankshaft B, pitman d,bar E, the upright a', the parallel cutters pivotally sus pended fromthe said bar E, the pivoted bar e2, and the leverfi, connecting one ofthe cutters with the bars E and e, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

EMMANUEL THOMAS COOK.
